A good rule of thumb for packing your suitcase—keep it light and comfortable. Follow these guidelines and you’re destined for a smooth getaway on and off the tarmac.

Light As Air

Thinner fabrics, and even minimal coverage undies, t-shirts, and socks will take up less space in your suitcase. If you’re feeling confident, thongs and jockstraps are as compact as you can get. Sleeveless t-shirts and tank tops fold smoother than shirts with sleeves. If you prefer full coverage, such as a v-neck or crew neck t-shirt, boxer shorts and briefs, opt for a thin, lightweight fabric such as modal or silk. Unless you’re traveling in winter temperatures, ankle socks or thin knit socks will squeeze into tighter spaces than a thick wool sock.
